The specific embodiment
Below, will be described in more detail the present invention by embodiment.These embodiment only are used for illustration the present invention, and the present invention's scope required for protection is not limited to these embodiment.
In this process, for the definition on illustrating and convenience, the thickness of the lines that illustrate in the accompanying drawing or the size of structural constituent etc. is compared reality and is exaggerated to some extent.And term described later is the term that defines in view of the function among the present invention, and it is explained can be different because of user, application person's intention or convention.Therefore, should give a definition to these terms based on the whole content of this specification sheets.
Fig. 2 is the block diagram for the structure of the steering controlling device of the vehicle of explanation one embodiment of the invention, and Fig. 3 is the figure for the increasing pressure curve curve after the compensation of explanation one embodiment of the invention.
With reference to Fig. 2, the steering controlling device of the vehicle of one embodiment of the invention comprises signal processing logic section 2, turns to logic section 3, increasing pressure curve dead area compensation logic section 4, Motor torque control part 5.
2 pairs of moments of torsion that require that keep ancillary system 1 to apply by lane of signal processing logic section carry out the signal processing.
Lane keeps ancillary system 1 to detect lane and the location information of the lane that detects is changed into the system that torque rating prevents the vehicle derailing lane by sensor (not shown) as a kind of, and it requires moment of torsion for applying to signal processing logic section 2 when the vehicle derailing lane.
The moment of torsion that requires that so applies exports the first calculation section 21 to by signal processing logic section 2.
Input torque calculates in the Calais with the moment of torsion that requires of chaufeur mutually with the moment of torsion that requires that receives from signal processing logic section 2 in the first calculation section 21, and this input torque exported to turns to logic section 3.
The moment of torsion that requires of chaufeur is the torque rating that is detected by torque sensor (not shown) when chaufeur carries out Vehicular turn.
Like this, the first calculation section 21 moment of torsion that requires that will work as chaufeur that chaufeur detect by torque sensor when rotating steering handwheel the Calais is exported input torque mutually with the moment of torsion that requires that is applied by lane maintenance ancillary system 1 when the vehicle derailing lane.
If turn to logic section 3 to receive input torque from the first calculation section 21, come the output motor moment of torsion with regard to applicable increasing pressure curve behind dead area compensation.
Above-mentionedly turn to logic section 3 to comprise for the increasing pressure curve 32 that input torque is exported to Motor torque and be used for the second calculation section 31 in the dead band of compensation booster curve 32.
Relevant dead area compensation, the output valve that is added to current increasing pressure curve by the compensation output valve from 4 outputs of increasing pressure curve dead area compensation logic section compensates.
Increasing pressure curve dead area compensation logic section 4 is used for the dead band that compensation turns to the increasing pressure curve of logic section 3, when lane keeps ancillary system 1 to be in the regular event state, increasing pressure curve dead area compensation logic section 4 can be worked, when starting, to the second calculation section 31 output compensation output valves that turn to logic section 3.
With reference to Fig. 3, the mode in the dead band of compensation booster curve is as follows: set the target slope of regulation, deduct the output torque value of current increasing pressure curve from the target slope, then its difference is added to the output valve of current increasing pressure curve.
The target slope is determined by tuning (tuning), tuning manner be under the subassembly state of electric steering-assisted system to electric steering-assisted system apply lane keep ancillary system require moment of torsion the time, judge based on speed of response and the reaction torque of deflection angle wheel.
For example, when apply lane keep ancillary system require moment of torsion the time, the time of deflection angle initial reaction can be set in the 500msec, and be below the 0.8Nm with the initial reaction torque setting.
That is, when lane keeps ancillary system to move, the dead band that is output as 0 increasing pressure curve in order to ensure advancing property is compensated, thereby even also can the normal reaction lane in low moment of torsion zone keep the moment of torsion that requires of ancillary system 1.
Motor torque control part 5 is used for applying Motor torque to motor (not shown) and controls and turn to, Motor torque control part 5 is from turning to logic section 3 to receive the Motor torque instructions, and controls with the Motor torque drive motor of institute's instruction and to turn to prevent the vehicle derailing lane.
Fig. 4 is the precedence diagram for the rotating direction control method of the vehicle of explanation one embodiment of the invention.
With reference to Fig. 4, if the vehicle derailing lane, then electric steering-assisted system receives by what lane kept that ancillary system (Lane Keeping Assistance System) 1 applies and requires moment of torsion (step S1).
Then, if applied the moment of torsion that requires of lane maintenance ancillary system 1, judge that then lane keeps the operating state (step S2～step S4) of ancillary system 1 energy.
Relevant lane keeps the judgement of the operating state of ancillary system 1, keep the diagnostic logic of ancillary system to judge that lane keeps the operating state of ancillary system 1 by the appropriateness that is used for judging CAN communication, the moment of torsion appropriateness of lane maintenance ancillary system 1 and the fitness of environment whether lane that lane keeps ancillary system, when being judged as all conditions when all normal, be judged as lane and keep the operating state of ancillary system 1 normal.
Keep the operating state of ancillary system normal if be judged as lane, then lane is kept the moment of torsion that requires that requires moment of torsion and chaufeur of ancillary system 1 to calculate input torque (step S5) in the Calais mutually.
Then, judge that again lane keeps the operating state (step S6) of ancillary system 1.
At this moment, keep the operating state of ancillary system 1 normal if be judged as lane, the then output of compensation booster curve (step S7).
The compensation output valve is determined by following formula:
The output valve of compensation output valve=target output value-current increasing pressure curve
Then the compensation output valve after will determining is added in the output valve of the current increasing pressure curve of exporting.
The output valve of Motor torque=current increasing pressure curve+compensation output valve
Namely, additionally will compensate in the output valve that output valve is added to current increasing pressure curve, even thereby also can obtain linear torque rating in the dead band of electric steering-assisted system, can when the vehicle derailing lane, apply Motor torque thus and prevent the vehicle derailing lane.
On the other hand, if be judged as the operating state mal that lane keeps ancillary system 1, then the increasing pressure curve before the applicable compensation comes output motor moment of torsion (step S8).
Then, the Motor torque of exporting is applied to control in the motor and turns to (step S9).
In sum, when lane keeps ancillary system 1 to move, the dead band that is output as 0 increasing pressure curve in order to ensure advancing property is compensated, thereby even can normally reflect also that in the low zone of moment of torsion lane keeps the moment of torsion that requires of ancillary system 1.
Like this, even the present invention also can keep the moment of torsion that requires of ancillary system to guarantee that lane keeps the performance that requires of ancillary system, can prevent the vehicle derailing lane thus by the correct response lane in the dead band of the electric steering-assisted system of setting for the advancing property of determining vehicle.
As mentioned above, the present invention is illustrated with reference to the embodiment that illustrates in the accompanying drawing, but this only is exemplary, and those skilled in the art in the invention should be appreciated that and can therefrom realize various deformation and other impartial embodiment.
